I am wondering if you have your cloud shadows turned off in this image? Multiple cloud layers? I ask because I think this is a very lovely image, but the far strata seems a little bleached out to me.
I have not seen a canyon IRL like this so maybe it is not.
It is very hard not to crank up the scale on great vegetation isn't it. I think yours looks pretty accurate or try a crop render with slight scale increases.
I tried a auto adjust color enhance, but got bluish cloud bottoms
I always try for that "post card" crisp look, haha.
